Suksdorfii ; it begins with the original description* and ends with 
its union to Oxalis corniculata var. (?) macrantha,f as in the case of 
its sister species. 
Mr. Nuttall collected his type in “ Woods around St. Barbara, 
California,” as is shown by his description and the label accom- 
Panying the type. The original specimen is sufficient to mark. it 
aS a very distinct species, and to support this I found an ample 
Specimen preserved in the Torrey herbarium, which agrees with 
Nuttall’s type in every particular.. This second specimen consists 
of two plants which were collected in the ‘ Valley of the Sacra- 
mento, California,” by Dr. Stillman. 
The gross characters which separate Oxalis pilosa from Oxalis 
Suksdorfii ate habit, the densely pale pilose pubescence found 
on the stems, petioles, peduncles and pedicels, and the longer col- 
umnar pods. The species doubtlesss occurs in many herbaria. I 
give the following description : 
Oxais Prtosa Nutt; T. & G. Fl. N. A. 1: 212. 1838. 
Perennial by a woody base, caulescent, stoutish, densely pilose 
roughout, pale green. Stem erect, ascending, or decumbent, 
1-3 dm. long, usually simple, woody below; leaves peltately 3-fol- 
lolate, 1-2 cm. broad, pilose on both sides; petioles slender, 2-6 
cm. long, with narrow dilated stipules ; leaflets mostly broader 
than long, sharply notched at the apex, ciliate, the lobes equal or 
nearly so; peduncles stoutish, surpassing the subtending leaves, 
topped by I~3 umbellate-cymose pedicels which are subtended by 
linear-subulate bracts; flowers yellow, nearly 2 cm. broad, rarely 
Solitary ; sepals ovate-lanceolate or oblong-lanceolate, 4-5 mm. 
long, obtuse, pilose; petals obovate, notched, 12-15 .mm. long ; 
filaments pilose; capsule columnar, 1.4—1.7 cm. long, abruptly 
Pointed, tipped by the spreading style-tips, clothed by a minute 
Stay pubescence, commonly longer than the reflexed pedicels ; 
Seed obovoid, 1.5 mm. long, marked with slightly interrupted 
transverse ridges. 
California, from the Valley of the Sacramento to Santa Barbara.
